G10 service notice

My G10 was subject to the recall. I called Canon. The tech asked me if I had experienced any of the lines in the images. I said that I had not. He told me that there was no reason to send the camera in. I asked if I could send it in in the future if I started seeing the problem. He said I could call them at anytime to return the camera for repair. What do you think? Should I wait or just send it in? Anyone have this problem?
